Xenocide

Loved it! Brilliant and thought-provoking!

This is a book that delves deeply into philosophy and metaphysics, even more deeply into religion (and why you shouldn't preach it to an alien race), and has no doubt left a lot of readers feeling a little uneasy as this book asks very difficult questions and challenges its readers.

Looking at those poor reviews I can only assume that this book (alongside the 2nd one) isn't for everyone, especially if you are expecting more like the first book. There is more philosophy than action, with the question of how do we eventually treat an alien species examined from just about every perspective, and in contrast with the first book which can be placed between the young adult genre, the 2nd and this one are definitely for the adult public.
I myself very much enjoyed the first 2 books in the series, and I think this one is the best so far.

On the other hand, Greg and Quara's character development is really poor (i guess intentionally), annoying brats.
